At time t = 0, terminal A in the circuit...

At time `t = 0`, terminal A in the circuit shown in the figure is connected to B by a key and an alternating current `I(t) = I_(0)cos (omega t)`, with `I_(0) = 1 A and (omega) = 500 rads^(-1)` starts flowing in it with the initial direction shown in the figure. At `t = (7pi//6omega)`, the key is switched from B to D. Now onwards only A and D are connected. A total charge Q flows from the battery to charge the capacitor fully. If `C=20(mu)F, R = 10(Omega) and the battery is ideal with emf of 50 V, identify the correct statement(s).
.

A

Magnitude of the maximum charge on the capacitor before `t=(7pi)/(6omega) "is" 1xx10^(-3)C`

B

The current in the left part of the circuit just before `t=(7pi)/(6omega)"is clockwise"`

C

Immediately after A is connected to D. the current in R is 10A.

D

`Q=2xx10^(-3)C`
